Gravity is typically conceptualized and understood by most sophont species by the end of the TL:1-3 technological epoch. By TL:4-6, gravity research becomes more theoretical culminating in prototype Gravity Control Technology by the end of TL:7-9 technological epoch.

TL:7-9: Gravity control is mostly theoretical at this stage although some society are able to create large, unwieldy gravcraft, which nevertheless work. Starcraft G-Drives become more and more capable.

While not often correlated by most people, historians have noted that the advent of practical fusion power plants is the result of applied gravitic compression of the fissionable fuels. Some mass-thrusters also rely on the gravitic compression of hydrogen to a near-fusion energy level. The ability to warp space-time and induce a jump is directly related to the control and understanding of gravitics. The Terran system failed to comprehend and use gravitics for many years, which delayed the Solomani expansion.
